Which US airport has the worst delay rate in 2026?

Newark (EWR) at 64.8 percent on-time, meaning 35 percent of arrivals are late. LaGuardia and Orlando follow at 66 to 68 percent.

Does flying through a bad-delay airport affect my compensation eligibility?

Eligibility depends on delay length and cause, not airport. But the probability of a qualifying disruption is much higher at EWR, LGA, or MCO.

Is the delay an airport's fault or the airline's fault?

Airport-level data shows combined delays. Airline-controllable (crew, mechanical) averages 22 percent of total delays; weather and NAS are the rest.

Does DOT compensate for weather delays?

DOT refunds apply to any 3+ hour delay regardless of cause. Additional compensation does not exist in DOT (unlike EU261/UK261). Trip delay insurance fills gaps for weather-covered expenses.

What's the first-flight-of-the-day advantage?

First wave at most airports has 15 percentage-point better on-time rates because cascading delays haven't started yet. Book early if on-time matters.

Should I avoid connecting through Newark?

If possible, yes. A 90+ minute buffer helps, but same-day cancel and delay risk is materially higher than non-NY hubs.

Are bad-weather airports good for insurance claims?

Trip delay insurance pays out by delay length, not airport. A 6+ hour delay at any airport triggers coverage, with no extraordinary circumstances exclusion for weather.

Worst US Airports for Delays

The worst US airports for delays in 2026 cluster in the Northeast, Florida, and California. Newark, LaGuardia, and Orlando lead by delay frequency, with BTS on-time rates below 68 percent. Here is the data and what it means for your claim.

The Bottom 10 Airports (2026 YTD)

Worst US airports for delays by BTS arrival on-time rate (2026 YTD):

›
EWR (Newark): 64.8 percent on-time.
›
LGA (LaGuardia): 66.2 percent.
›
MCO (Orlando): 67.5 percent.
›
SFO (San Francisco): 68.1 percent.
›
JFK (New York): 69.0 percent.
›
ORD (Chicago O'Hare): 69.4 percent.
›
DCA (Washington Reagan): 70.2 percent.
›
BOS (Boston): 70.8 percent.
›
FLL (Fort Lauderdale): 71.0 percent.
›
LAX (Los Angeles): 71.4 percent.

Newark's 64.8 percent means 35 percent of arriving flights are late. That compounds into disproportionate delay claim volume for any route through EWR.

Why These Airports Lag

›
EWR/LGA/JFK: NY airspace congestion, weather volatility, old infrastructure.
›
MCO/FLL: Florida summer thunderstorm density and heavy peak-season volume.
›
SFO: marine layer and runway parallel-spacing FAA restrictions in poor visibility.
›
ORD: weather, volume, and hub-bank compression by United and American.
›
DCA: congestion slot restrictions and short runway constraints.
›
LAX: gate constraints and operational complexity at 4 terminals.

Delay Causes by Category (2026)

›
Late aircraft (cascading): 32 percent.
›
Carrier-controllable: 22 percent.
›
Weather: 27 percent.
›
National Aviation System (NAS): 16 percent.
›
Security: 1 percent.
›
Other: 2 percent.

Airline-controllable is what matters for compensation. At EWR and LGA, 24 to 28 percent of delays are controllable (above the 22 percent average), making those airports especially claim-rich.

What This Means for DOT Refund Claims

Under the DOT 2024 refund rule, any cancelled flight or significantly delayed flight (3+ hours domestic) triggers a cash refund regardless of cause. The worst-airport data matters because the probability of a qualifying disruption is dramatically higher. A Newark-hubbed itinerary has a 35 percent chance of arrival disruption on any given day.

Avoiding the Worst-Airport Penalty

›
First flight of the day: on-time rates 15 percentage points higher than evening.
›
Midweek departures: Tue, Wed, Thu historically better.
›
Non-hub routing: avoid connecting through ORD, EWR, LAX when possible.
›
Southwest-heavy airports: check the airline breakdown, not just the airport.
›
Long minimum connection: 90+ minutes buffer at EWR, LGA, SFO.
